A column (compression member) in the upper story of a building is subject to the following loads: Dead load: Floor live load: 46 kips compression Roof live load: 19 kips compression 109 kips compression com Snow: 20 kips compression a. Determine the controlling load combination for LRFD and the correspond- ing factored load. b. If the resistance factor o is 0.90, what is the required nominal strength? c. Determine the controlling load combination for ASD and the corresponding required service load strength. d. If the safety factor 2 is 1.67, what is the required nominal strength based on the required service load strength?
